Contributions to these notes are very much appreciated; anything from one-character typo corrections to new chapters or rewrites. The GitHub repository for this project provides a Pull Request system for submitting contributions. See https://happygitwithr.com/pr-extend for an explanation of the pull request system and the available R utility functions for working with pull requests.

K.1 Style guide

  • Every abstract concept (definition or theorem) should have at least one concrete example immediately following it.

  • More structure (headers, labels) is better.

  • Make each conceptual chunk as compact as possible:

    • Decompose large, complicated, difficult concepts into smaller, simpler, and easier pieces.
    • Decompose long derivations into smaller lemmas.
    • When manipulating part of a larger expression, isolate that part in a lemma.

K.2 Fixing typos

This book is written using Quarto. You can fix typos, spelling mistakes, or grammatical errors directly using the GitHub web interface by making changes in the corresponding source file. This generally means you’ll need to edit a .qmd file.

K.3 Bigger changes

If you want to make a bigger change, it’s a good idea to first file an issue and make sure someone from the development team agrees that it’s needed.

K.3.1 Pull request process

  • Fork the package and clone onto your computer. If you haven’t done this before, we recommend using usethis::create_from_github("d-morrison/rme", fork = TRUE).

  • Install all development dependencies with devtools::install_dev_deps(). Make sure you can build the book by running quarto render in a Terminal.

  • Create a Git branch for your pull request (PR). We recommend using usethis::pr_init("brief-description-of-change"). Details at https://usethis.r-lib.org/articles/pr-functions.html

  • Make your changes, commit to git, and then create a PR by running usethis::pr_push(), and following the prompts in your browser. The title of your PR should briefly describe the change. The body of your PR should contain Fixes #issue-number.

  • Add a bullet to the top of NEWS.md (i.e. just below the first header). Follow the style described in https://style.tidyverse.org/news.html.

K.3.2 Code style

  • New code should follow the tidyverse style guide. You can use the styler package to apply these styles, but please don’t restyle code that has nothing to do with your PR.

K.4 Code of Conduct

Please note that the rme project is released with a Contributor Code of Conduct. By contributing to this project you agree to abide by its terms.

K.5 Additional references

For a detailed discussion on contributing to this and other projects, please see the Tidyverse development contributing guide and the Tidyverse code review principles. This project is not part of the tidyverse, but we have borrowed their development processes.
